Yeah, it was basically a question of how ifconfig parses its command
line and issues ioctl's to the driver in order..

Not sure what it is, but it's unrelated. It happens on at least ral(4),
too. I need to try wi(4) again since ath(4) started losing this way.

Absolutely. The other slot in the same laptop is normally occupied by
a 3com 10/100 ethernet and modem combo. Because the modem is wired to
the internal speaker, I can hear it tick each time it is powered up;
this happens for device probing, ttyflags during rc, and whenever I
open the tty or bring up the ethernet.
There have been tweaks and improvements to the details (power up wait
times, for example) over the years, but it's worked this way in NetBSD
basically since pcmcia/cardbus support was added.
